Abstract :
When X-cut lithium tantalate plates are oscillating at overtones of the strongly excited thickness quasi-shear mode, the resonant frequencies are found to have frequency-temperature coefficients of about -40 ppm/°C. Such frequency-temperature coefficient limit the usefulness of X-cut lithium tantalate in wide-band filter applications.
